Hi,
when you say you have installed lejos, did you go through the build part of the install? Did it work? Can you provide an ls -l of your leJOS bin dir. Also what version of Java are you using. I would recommend the Sun version. If you run lsusb -l with the NXT on and connected do you see the Lego device in the output?

Hi again,
Also if the ant build is not completing you would be better to remove that Bluetooth part of the build. The ant script installs the files to the correct location and also sets permissions etc. You can probably do this by hand (take a look at the ant scipt and check that you are doing the correct thing) but it is probably better to get the ant script to work correctly on your system...
